Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 A direction view;
Fig. 3 is the structural representation of standard component of the present utility model.
Embodiment
For can technical characteristic of the present utility model and effect be described in detail, and can realize according to the content of this instructions, below in conjunction with accompanying drawing, embodiment of the present utility model be further illustrated.
Fig. 1 illustrates the embodiment of a kind of steam seal ring machining deformation amount detecting device in the numerous embodiment of the utility model.This steam seal ring machining deformation amount detecting device comprises standard component 5, monitor station 1, keeper 4, instrument fabricated section 3 and measurement mechanism 2.
Monitor station 1 has work wall 11, and work wall 11 is horizontally disposed better.
In the lump see Fig. 2 and Fig. 3, keeper 4 can be but be not limited to register pin.In the present embodiment, keeper 4 is three register pins, and it is the work wall 11 that arcuation is arranged at intervals at monitor station 1, and one is wherein movably set in work wall 11, and all the other two are fixed on work wall 11.During detection, these keepers 4 are all positioned at standard component 5 extrados or tested steam seal ring 6 extrados side, for against standard component 5 extrados or tested steam seal ring 6 extrados.
Instrument fabricated section 3 is arranged at work wall 11.During detection, be positioned at standard component 5 intrados or tested steam seal ring 6 intrados side.In the present embodiment, instrument fabricated section 3 is three.Each instrument fabricated section 3 comprises the bearing 31 being arranged at work wall 11 and the handwheel 32 be flexibly connected with bearing 31 for putting measurement mechanism 2, and handwheel 32 is flexibly connected with bearing 31 by screw thread pair.By rotation hand wheel 32, measurement mechanism 2 can be regulated if dial gauge is relative to being positioned at standard component 5 intrados or tested steam seal ring 6 intrados moves back and forth.
Measurement mechanism 2 is three, and one_to_one corresponding is arranged at instrument fabricated section 3 respectively.During detection, for measurement standard part 5 intrados and the tested steam seal ring 6 intrados distance relative to corresponding instrument fabricated section 3, the numerical value measuring gained can be relative value, also can be absolute figure.Measurement mechanism 2 can be but be not limited to dial gauge, and when measurement mechanism 2 is dial gauge, preferably, the axis of its sounding rod extends along the radial direction of measurement standard part 5 intrados or tested steam seal ring 6 intrados.
The structure of standard component 5 is identical with steam seal ring 6 structure of standard, compares for detecting.
It is better that instrument fabricated section 3 is movably set in work wall 11, to adapt to detect all kinds of specification steam seal ring 6.
